Today I've had the oppertunity to try the new 200-400/4 IS with the 1.4x converter

I've never tried any longer lens than the 70-200/2.8 II IS, so it was quite amazing to have the oppertunity to try this one out. The place had quite bad lightning aswell so I had to use ISO 12.800 on the 5d3, but the images looked very nice.I really like the fact that I could switch on the 1.4 so easily and the lens felt very "light" (as far as I could tell).. but very well built!

I've attached a picture of me trying it out with the 5d3 here. Have some more pictures on my phone. Have to bring my own 5d3 tomorrow to try it some more!

I'm tempted, and I can "afford" it, meaning if I really want it I can pay cash and not hurt myself financially. Just don't know if I want it that bad.

The neat thing is that in one lens you have a lot of options obviously, 200-800ish if you use the internal and external converters. Seems like an excessive purchase though, I'd need to go on a safari or something to justify it

It's not that heavy at all. I was quite surprised when I held it that it felt quite good with the weight. No problem hand-holding it for me, even though my techniqes was not the very best for the quick shooting that I did

When I tried it last March at Focus on Imaging, it felt similar in weight to the MkI version of the 300 f/2.8 L IS, but it could have been down to better balance on the 1D IV it was attached to also.
